What Topics Should You Study?

A successful preparation plan covers every major exam objective rather than focusing only on practice questions.

SQL Fundamentals

Learn how relational databases work, understand tables, columns, rows, primary keys, foreign keys, and Oracle database terminology.

Retrieving Data

Practice writing SQL queries using:

  • SELECT statements
  • WHERE conditions
  • ORDER BY
  • DISTINCT
  • Aliases
  • Operators

These basics appear throughout the exam.

SQL Functions

Become comfortable using:

  • Character functions
  • Number functions
  • Date functions
  • Conversion functions
  • Aggregate functions
  • Group functions

Understanding when to use each function is essential.

Working with Multiple Tables

One of the most important exam areas includes:

  • INNER JOIN
  • LEFT JOIN
  • RIGHT JOIN
  • SELF JOIN
  • CROSS JOIN
  • Set operators

Expect scenario-based questions involving relationships between multiple tables.

Data Manipulation Language (DML)

Practice statements such as:

  • INSERT
  • UPDATE
  • DELETE
  • MERGE

Know how transactions work, including COMMIT, ROLLBACK, and SAVEPOINT.

Database Objects

Understand how Oracle uses:

  • Views
  • Sequences
  • Synonyms
  • Indexes
  • Constraints

Learn why each object exists and when it should be used.

Practice Yourself Instead of Memorizing

The best way to prepare is by writing SQL queries daily. Create sample databases and practice solving business problems such as:

  • Finding top-selling products
  • Joining customer and order tables
  • Calculating monthly sales totals
  • Filtering employee records
  • Creating summary reports

Hands-on experience improves both speed and accuracy during the exam.

Effective Study Plan

Week 1

  • Learn SQL syntax
  • Practice basic SELECT statements
  • Understand filtering and sorting

Week 2

  • Study joins and subqueries
  • Work with aggregate functions
  • Practice GROUP BY and HAVING

Week 3

  • Learn DML commands
  • Study transactions
  • Review constraints and database objects

Week 4

  • Complete full-length practice exams
  • Analyze incorrect answers
  • Focus on weak topics
  • Practice writing SQL without referring to notes

Common Mistakes Candidates Make

Many candidates struggle because they:

  • Memorize answers instead of understanding SQL logic.
  • Ignore Oracle-specific syntax.
  • Spend too little time practicing joins.
  • Forget transaction control commands.
  • Avoid writing SQL queries manually.

Building practical SQL skills is the most reliable way to pass the exam.

Frequently Asked Questions

Is the 1Z0-071 exam difficult?

The difficulty depends on your SQL experience. Candidates who regularly practice writing SQL statements generally find the exam much more manageable than those who rely only on reading study material.

Do I need programming experience?

No. Basic database knowledge is helpful, but the exam focuses on SQL rather than general programming languages.

How much practice is enough?

Aim to write SQL queries every day and complete multiple timed practice exams. Reviewing the explanations behind incorrect answers is just as important as answering correctly.

Should I study Oracle-specific features?

Yes. While SQL concepts are transferable across database platforms, the exam emphasizes Oracle Database syntax and functionality, so it's important to become familiar with Oracle-specific commands and behavior.
